To all a0/om t may concern.' Y t itlniown that l, ANDREW] l1. Weis, a`

citizen of the United States of America, `and a resident of Monroe,Michigan, have invent` f ed a certain new and"u`seful Improvement inPaper oXes or Similar Containers, of which the following isaspecification.t` y

This invention relates to paper boxes of that kind in which the entirebox, preferlO ably, is madefroin a single blank having foldablyconnected sections to form the side walls, and flaps to form the top andbots tom.

t Generally stated, the object of the invenl5 tion is to providea boxwhich can be shipped tlat, andwhich can be' readily reduced to acondition suitable for use by the folding` and securing in place of theflaps which form` the bottom, `so that thebox can be filled withtobaccoor some other commodity,

and which can then be readily closed by se curing the upper Haps inplace,` the ,lower flaps being practicallyloclred against opening, afterthe bottom is once closed, but the t W other flaps being capable ofunfolding to remove the contents thereof.`

` `It" is'also an object to provide certain detailsand features ofconstruction tending to openthe top ofthe boX when it is desired toincrease the general etliciency and the desiraility of a boX of thisparticular construction. M

To these and other `useful" ends the invention consists in mattershereinafter set forth' andclaimed, and shown in th accompany# ingdrawings, in'which- Fig. `1 is a perspective of `a bor` embodying theprinciples of the invention, showing `the top thereofopen.

lFig. 8 is a horizontal section on line 8-8 9 is a horizontal section online 9-1-9 in Fig. 7.

As thus illustrated, and `referring to Fig.

5, it will be seen that the blank from which the box is made comprisesthe rectangular G0 sections 1, 2, 3, 4l, 5, and 6, which are iiexiblyconnected together by the creasesor score lines 7, 8, 9, 10 and 11, thesections l, 2 and et being broad to form the front and back of the box,while the sections 3 and 5 are nar- 65 row to forinthe narrow sides ofthe box. The section lhas a half-nioon-shaped opening 12 therein, nearits lower edge, and said lower edge has a flap 13 secured thereto alongthe flexible crease or score line 14, while the section 2 has a curvedslot 15 therein near its upper edge.V The section 8 is provided withupper and lower flaps `16 and 17,. and the section 5 has upper and lowerHaps 18 and 19, while the section 4l 75` has upper and lower flaps 20and 21; and the liaps16 18 and 20 are connected to their respectivesections along "the crease or score line 22, while the flaps 17, 19 `and21 are cont nected to'these sections along the score line 80 23, so thatthe flaps may be folded ashere-` inafter described. For the purpose ofclos-- ing thetop ofthe box, as hereinafter explained, theflap 20 has acrease or scoreline t 24;, and forthe same purpose the flap 21 has 85 acreaseor score line 25, and in addition the flap 21 is cnt through` at26, and in` this way the half-rno`on-shaped portion E27V can be pressedslightly inward, so` that it twill cooperate withthe opening 12, in themanner hereinafter `set forth. f

` With a `blank of the foregoing character, the `box is inade in thefactory to the extent that the blanks are formed and partially set v upor put together, the sections 1 and 2 95 being folded flatwise together,and the free edge of the section 1 being glued or otherwise securedalong the inner surface of the section 2 adjacent the fold line 8, sothat the sections provide a double wall; the section 6 is then glued orotherwise secured to the section 1j alongthe fold `line 7, whereby a boxwhich is flat and rectangular in cross-section is provided. The hollowstructure thus formed, however, can be flattened 'down when in thiscondition, which will reduce the expense of transportation. 'lhe userwill then open it up, fold the flaps 17 and 19 upward, fold the flap 13npward against the Haps 17 and '19, 110

and then fold the flap 21 upward and in sert its edge between the outerwall 2 and the inner wall 1, this liep being' folded along` the line 25where it engages the lower edge of the wall 1, whereby the bottom isclosed. rllhe portion 27 having been displaced inwardly, its straightedge will dro-p into the space formed by the opening 12 and will engagethe straight edge of the latter, thus formino4 a locking` device to holdthe bottom flaps in closed position. As the walls l and 2 are heldflatwfise to gether, the interlocking' iiap 21 cannot be withdrawnexcept by forcibly pulling it out, which would Vtear the paper, or bysqueezing the box in a manner to spring the walls 1 and 2 apartsuiiiciently to disengage the portion 27 `from the opening 12, so thatthe bottom or lower end of the box is practically closed permanentlyafter the flaps are properly folded'. This, however, leaves the top ofthe box open. and the tobacco or other commodity can then be placedtherein. J-Alfter that, the flaps 16` and 18 can be folded downward, andthe flap 2O can be folded downward, so that it willbend along its creaseor score line. 24 where fit engages the upper edges of the walls 1 and2, and the tongue-shaped portion of the iiap 20 can then be inserteddownwardly through theslot 15 and between the walls 1 and 2y to closethe top of the box. However, the tongue portion of the flap 2O can `bewithdrawn from the slot 15 when it is desired to open. the box for thepurpose of removing the contents thereof. y

In Fig. 6 theconstruction is similar to that previously shown, exceptthat the lower closing flap 28 of the box is providedr with twotongue-shaped portions 29 pressed from the body portion thereof, whichare adapted to engage the rectangular openings 30 formed in the innerwall 31, which latter corresponds to the inner wall 1 of theconstructionl previously de scribed. In this way, .the tongues or smallflaps 29 cooperate with the openings 30 to practically permanently closethe bottom of the box. In Fig. 7 the construction is similar-to thatpreviously described, but in this case4 the opening 12 previouslydescribed is engaged lbyr a corrugated tonguer or inwardly displacedportion 32 which` is pressed from thebo'dy-portionof the flap ,3.3,which latter corresponds to the ilap 21 previously described. Y y

Other modificationsY will beobvious, ,but inanyzeventthe box, asonefeature of. the llv'ent'll, iS adapted to be shipped Het, afterthe blankis partially folded, and is provided with bottomilaps which can befolded Yto interlock to close the bottom, and with top flaps which. canalso be folded to close top after the tobacco .or-other .cornmodity isplaced in the box. Thus a. saving in transportation is accomplished, asthe boxes can be packed tightly together without any waste space.

Thus it will be seen that the flap 28 or the flap 33 or the flap 21, ineach form of the invention, has an interlocking connection with theinner thickness of a twoply or doublev thickness wall, so that thecatch, or interlocking connection thus formed is inaccessible from theoutside of thc box` whereby this interlockingr connection cannot bedisturbed after the box is filled, the bottom of the box beingpractically closed permanently in this way.
